Definitions

  • Conventional techniques for providing lubrication and/or coolant to cutting edges of cutting inserts typically involve introducing the coolant via openings in a toolholder for the cutting insert, or via spray nozzles directed at the cutting edges such as US 4,848,198 .
  • Some cutting inserts include channels formed in the cutting inserts that are in flow communication with and facilitate introduction of coolant from channels provided in the toolholder body.
  • EP2789415 on which the preamble of claim 1 is based, discloses cutting tools with an insert clamp having fluid flow passage.
  • a tool comprises a holder body having a pocket, a clamping means in the shape of a locking member, a cutting insert and a nozzle, said nozzle having a single through hole for a fastening member, said nozzle having a forward end, a rear end and a bottom face, said through hole extending between the bottom face and an opposite top face, at least one internal coolant channel being provided in the nozzle and extending from a first opening to a second opening, said first opening connecting to a coolant supply conduit in the holder body, said second opening serving as exit for the coolant at the forward end, wherein the at least one coolant channel and the first opening are spaced from the through hole to avoid interference therewith.
  • the bottom face of the nozzle comprises a guide device such as a projection or recess adjacent to the forward end to set the direction of the nozzle by having the guide device cooperating with a recess or projection on the clamping means to secure that coolant direction for optimal performance always is the same when indexing or changing inserts.
  • a guide device such as a projection or recess adjacent to the forward end to set the direction of the nozzle by having the guide device cooperating with a recess or projection on the clamping means to secure that coolant direction for optimal performance always is the same when indexing or changing inserts.
  • the nozzle has a longitudinal axis that intersects the through hole to be able to function as a lever, and the nozzle exhibits mirror symmetry about a plane containing a longitudinal axis of the nozzle to increase versatility.
  • the first opening is located at a portion of the bottom face, said portion projecting such that a tangent to the bottom face perpendicular to a through hole axis intersects the first opening to thereby make sure the first opening is positioned close to the coolant supply conduit.
  • the nozzle is a removable nozzle for turning applications where coolant cools the cutting insert and the tool comprises means to coolant-tightly seal the nozzle relative to the holder body to avoid leakage of coolant.
  • the first opening is situated between the through hole and the rear end to make more space for fastening means.
  • the coolant channel or the first opening is surrounded by a seal such as an O-ring.
  • the nozzle is a one-piece unit preferably made through additive manufacturing, such that it has no plugged holes.
  • the fastening member is a screw which extends along a hole in the holder body, said screw being intersected by upper and lower imaginary planes of the cutting insert.
  • the nozzle acts as a clamp pressing against a part of the cutting insert.
  • a single fastening member or screw secures both the cutting insert and the nozzle.
  • the shown cutting tool 1 may be a turning tool for internal metal machining and comprises a holder body 2 having a pocket 3, a clamping means in the shape of a locking member 4 and an inducer or nozzle 10.
  • the pocket 3 is conventional and may have a bottom surface 7 and two upstanding walls 6A and 6B.
  • the bottom surface 7 may have a recess 8 to accommodate the locking member 4.
  • the bottom surface may be provided with a removable shim, not shown.
  • the recess 8 is key lock shaped in top view, e.g. a combination of a circle and a rectangle, and may have a ledge 9 below about a center of the bottom surface 7.
  • the indexable cutting insert 5 is clamped in the pocket by means of an L-shaped locking member 4 projecting into a hole of the cutting insert.
  • the cutting insert and pocket are generally diamond in shape but may have other shapes.
  • the L-shaped locking member urges the converging sides of the cutting insert 5 against upstanding walls 6A and 6B, which are of substantially complementary shape to the sides of the cutting insert.
  • the locking member forms one leg 4B of an L-shape pivotally arranged in the recess 8 in the holder 2, the other leg 4A of which member extends through a hole of the cutting insert 5.
  • the locking member may have a rim 4D which rests upon the ledge 9 in the recess 8.
  • Actuating means or fastening means 12 is provided to move the leg 4B downwardly and by this cause a pivoting action of the locking member around an axis and about a fulcrum point of the rim 4D and the ledge 9.
  • the said axis forms substantially a right angle with the direction in which the leg 4B extends.
  • the means 12 is in the form of a screw 12A threadably engaged in a hole 12B in the holder 2.
  • the screw 12A may have a single threaded end portion and may have an end portion arranged to engage the free end 4C of the leg 4B of the L-shaped locking member 4, when the screw 12A is turned, to cause said pivoting action of the locking member around the fulcrum point formed in the holder 2.
  • the leg 4A passes through the recess 8 in the holder, the opening being shaped and dimensioned so as not to impede desired pivotal movement of the legs.
  • the locking member leg 4A extends into a central hole in the cutting insert and serves to detachably secure the cutting insert in the pocket 3. The pivotal movement of the leg 4A causes the cutting insert 5 to move towards the walls 6A and 6B and be clamped thereto.
  • the screw 12A may extend along a hole 12B in the holder body 2.
  • the screw is intersected by upper (P1) and lower (P2) imaginary planes of the cutting insert.
  • the planes P1 and P2 may be parallel and each plane may touch at least two, preferably three or four, corner portions of the upper and lower surface of the cutting insert, respectively.
  • the nozzle 10 exhibits mirror symmetry about a first plane P3 containing a longitudinal axis A of the nozzle as can be seen, for example, in FIG. 1D .
  • the nozzle may be a one-piece unit.
  • the nozzle includes a forward end 13, a rear end 14 and a bottom face 15.
  • the bottom face 15 comprises a first surface 15A and a second surface 15B, the first surface being generally recessed relative to the second surface.
  • a single through hole 11 extends between the bottom face 15 or the second surface 15B and an opposite top face 16.
  • the single through hole 11 may be surrounded by an enlarged cavity 11A at the top face 16.
  • At least one internal coolant channel 17 is provided in the nozzle that extends from a first opening 18 to a second opening 19, and is preferably not having any strength reducing or plugged holes such as stop screws in holes.
  • internal coolant channel is here primarily meant self-contained channels where the walls of the channel are within the nozzle.
  • the first opening 18 is connectable to the coolant supply conduit 20 in the holder body.
  • the first opening 18 is located at the second surface 15B of the bottom face 15.
  • the second surface 15B projects such that a tangent T to the first surface 15A facing the cutting insert 5, and perpendicular to a through hole axis intersects the first opening or the channel 17.
  • the first opening 18 is positioned between the through hole 11 and the rear end 13 and may comprise a chamber 26 in flow communication with the second opening 19.
  • the second opening 19 serves as exit for the coolant at the forward end 13.
  • the at least one coolant channel 17 and the first opening 18 are spaced from, i.e. not in contact with the through hole 11.
  • the at least one coolant channel 17 may follow a smooth path without sudden directional changes such that coolant flow is not obstructed.
  • At least a first portion 21 of the coolant channel 17 transits mathematically smooth or continuous into a second portion 22 of the coolant channel.
  • the first and second portions of the coolant channel are designed such that first derivatives thereof are continuous if their lower peripheries are seen as mathematical curves for example as in the top view of Fig. 1C . Thereby, there will be reduced risk for oil traps when using oil mist as coolant.
  • the nozzle 10 is made through precision casting or additive manufacturing such as metal 3D printing processes which use binders, or fully dense metal processes like selective laser sintering (SLS) or direct metal laser sintering (DMLS).
  • SLS selective laser sintering
  • DMLS direct metal laser sintering
  • the latter technology uses a high power laser to fuse small particles of metal powders into a nozzle that has the described three dimensional shape.
  • the laser selectively fuses the powdered metal by scanning the crosssections (or layers) generated by a three dimensional modeling program on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness. Then a new layer of material is applied on top and the process is repeated until the nozzle is completed.
  • the nozzle 10 can be held to the holder body by the fastening member 12, preferably by the screw 12A.
  • the single through hole 11 receives the fastening member 12 carrying a spring 30 and that is threadedly secured to a hole 12B in the holder body.
  • the cavity 11A bottom 11B is intended to serve as a seat for the spring 30, such as a multiwave compression spring of for example stainless steel. Multiwave compression springs may be used in applications where space problems in length preclude the option of using a normal compression spring.
  • the spring 30 is more closely shown in FIG. 1J . Other spring means can be used such as rubber washers.
  • the nozzle does not have a front projection to engage a wall of the through hole of the cutting insert.
  • the coolant is led through conduits passing through the holder body and requires connecting passageways and a deformable seal to lead the coolant to a discharge exit 19.
  • the fastening member 12 may have a head 12C which has an underside that can act on the spring 30 and urge the nozzle towards the holder.
  • a seal element 25, such as an O-ring may be secured to or be loosely held by the nozzle or be secured to or be loosely held by a concave cavity 20A surrounding the conduit 20 opening in the holder body 2.
  • the seal element 25 may be compressed between the nozzle and the holder body during the tightening of the fastening member to coolant-tightly seal the conduit 20 opening.
  • the screw head 12C will act on the spring means 30 and force the nozzle in direction towards the holder body.
  • the nozzle will become clamped against the holder body via the interaction of the seal 25 and the concave cavity 20A.
  • the nozzle first surface 15A is spaced from, i.e. not in contact with the cutting insert 5 in assembled state.
  • the holder body and/or the nozzle may be provided with means to guide the nozzle to a desired direction, such as protrusions acting peripherally on the nozzle or at least one protrusion acting in the forward end of the nozzle acting centrally on the cutting insert.
  • the nozzle in this embodiment is not meant to clamp on the cutting insert but can do so if for example a thicker O-ring is used instead of the O-ring 25 shown. In the latter case the nozzle will tilt about an axis perpendicular to the length axis A and the forward end thereof will contact the cutting insert.
  • the shown tool will be turning metal workpieces while coolant may flow in order through the holder body 2, the coolant supply conduit 20, the seal 30, the fluid channel 17 and from the exit 19 to at least one active cutting edge.
  • a single fastening member 12 or screw 12A secures both the cutting insert 5 and the nozzle 10.
  • FIGS. 2A to 2L show a cutting tool 1' according to the present invention.

  • the locking member has one leg 4B' of the L-shape pivotally arranged in the recess 8' in the holder 2', the other leg 4A' of which member extends through the hole of the cutting insert 5'.
  • a free end of the leg 4A' has a recess 29', such as a blind hole.
  • the locking member may have a rim 4D' which rests upon the ledge 9' in the recess 8.
  • Actuating means or fastening means 12' is provided to move the leg 4B' downwardly and by this cause a pivoting action of the locking member around an axis and about a fulcrum point of the rim 4D' and the ledge 9'.
